To allwhom it ma/y concern: l

Beit known that I, ANDREW SMITH HAL-l LIDIE, of l SanFrancisco, in the county of San Francisco and in the State of California, have Way, of'A which the following is a specificag had 'to the accompany- This invention relates to that class of endless wire rope-waysor wire tram-ways in which the buckets or cars are secured by means of suspension-rods to hangers or carriers that rest like a saddle upon therope, and are lifted f'romthe carried bythe momentum of the moving parts passing; but when the bearing pulleys are placed at considerable distances apart, or when the rope is slack the part nearest the pulleys is `so much inclined or forms so great an angle with the horizontal that the momentum is somehorizontal. The object of' my invention is, first, toprovide a more positive and reliable meth-A odlof carrying the saddle over the bearingpulleys; second, to so improve the saddle or hanger that it will firmly; hold therope when lifted Cif when passing the pulleys.4 The first I accomplish by bringing the saddle or hanger into contact with `the bearingpulley in such a manner that thelatter, revolving continually side. `The second object l accomplish by the in clip or gripe pulleys, inserted in the saddle greater part of the `weight of the hanger and sainewhen the weight is removed.

In the drawing, Figure lis a side elevation of a bearing-pulley and saddle having my improvements, showing the rope resting in the groove of the bearingpulley and the saddle in the act of passing over the top of the pulley. Fig. 2 is a transverse section throughfthe center of' Fig. l. Fig. 3 is a longitudinal section through the center of saddle, shown in Fig. l, resting upon the rope, showing one clip in position. Figs.`4 and 5 represent a saddle in which two pairs of clips are employed.

Each part is distinguished by the same letter Whenever it appears in the drawing.

A is the saddle, provided with a single pair of clips, B, placed in the center of its length and immediately below the point at which the suspension-rods are attached. With a single pair of clips the -saddle must be sufficiently long to prevent the possibility of turning end -over end, or the suspension-rods must be attached below the level of the rope instead of' above it, as shown in the drawing. When two `pairs of' clips are used they must be placed sufficiently far apart to avoid the same danger. C is the `bearing-pulley, having projecting cylinders D upon each side, about equal in diameter to twice the distance from the center of the rope to the center of the wheel; The V.inner faces E of the side plates F of the sadvdle are vertical, and fit the sides of that part of the pulley embraced by them, and thereby act as guides in passing over. The lower faces ner that when the saddle approaches the pulley they will come in contact with the cylinders D, and, being carried by the friction of' that Contact or by suitable teeth or projecor V-shaped part ofthe saddle clearof the top of the pulley in passing. `When two saddles, A, are employed, linked or fastened together at such a distance from each other that one pair of'1 clips would always rest upon the rope whilethe other is passing over, no teeth would be required either upon the faces of the cylinder D or upon the lower faces of the side plates F. When wheels are attached to the saddles for running over rails placed in such a position as to raisenthe saddle over the pulleys, the clips may be incased, as shown in Figs. 4 and 5.

of the side plates F are curved in such a man` tions over the pulley, they will raise-the clips p 3.. The saddle or hanger substantially as described, and'for the purposes set forth.

4. The employment of clips B, or their equivalent, in the saddle or hanger of an endless wire rope way, substantially as herein described, and for the purposes herein set forth.

In testimony whereof' I have hereunto set my hand this 7th day of February, A. D. 1871.
